Question

$bx^{2} + cx + a = 0$

• A. { – 1, 2}
• B. {1, 2}
• C. { – 1, – 2}
• D. {1, – 2}

Answer 1

Answer: (D)

{1, – 2}

Answer 2

$x^{2} + xe - e = 0x = \sqrt{6 + \sqrt{6 + \sqrt{6 + ....\text{to}\infty}},}$ or $2 < x < 3$

$x = 3$ or $x^{2} + 5|x| + 4 = 0$ $\log_{4}\{\log_{2}(\sqrt{x + 8} - \sqrt{x})\} = 0$

$\{ x \in R:|x - 2| = x^{2}\} =$does not gives any real root]
